Geometrically defined asymptotic coordinates in General Relativity
Carla Cederbaum, Jan Metzger
We review and announce recent results on the asymptotic behavior of asymptotically Euclidean relativistic initial data sets and asymptotic foliations thereof. In particular, we dis…
Trapped photon region in the phase space of sub-extremal Kerr-Newman and Kerr-Sen spacetimes
Carla Cederbaum, Karim Mosani
We analyse the geometry and topology of the trapped photon region in the domain of outer communication of sub-extremal Kerr-Newman and Kerr-Sen spacetimes. Specifically, we show th…
Uniqueness of static vacuum asymptotically flat black holes and equipotential photon surfaces in dimensions à la Robinson
Carla Cederbaum, Albachiara Cogo, Benedito Leandro +1
In this paper, we combine and generalize to higher dimensions the approaches to proving the uniqueness of connected (3+1)-dimensional static vacuum asymptotically flat black hole s…
Uniqueness of equipotential photon surfaces in 4-dimensional static vacuum asymptotically flat spacetimes for positive, negative, and zero mass -- and a new partial proof of the Willmore inequality
Carla Cederbaum, Albachiara Cogo, Axel Fehrenbach
We present different proofs of the uniqueness of 4-dimensional static vacuum asymptotically flat spacetimes containing a connected equipotential photon surface or in particular a c…
